CLOTHES-WRINGER.

To all whom it may concern:

Be it known that I, GEORGE B. GRIFFIN, of Madison, in the county of Daneand State of IVisconsin, have invented certain new and usefulImprovements in Clotlies-lmingers; and I do hereby declare that thefollowing is a full and exact description of the same, reference beinghad to the accompanying drawings, and to the letters of reference markedthereon, in which- Figure l is a front elevation. Fig. 2 is a verticalsection of the entire machine, and Fig. 3 is a perspective view of aportion.

Y Similar letters of reference denote like parts in all the drawings.

My improved wringer is adapted to be fixed upon a tub or upon a conicaltinted vessel such as is used in the washing machine generally known asFrenchs patent, patented to Mr. IVitsell Jan. 25th 1859.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation by the aid of thedrawings.

I employ a frame composed of two uprights of wood, A, A, fastenedtogether in the ordinary manner by cross bars. The bases of theuprightsf A, A, are forked .to sit astride of the edge of a tub orsimilar vessel. In suitable bearings in A, A, are mounted the shafts oftwo rollers- B, C, composed of hollow cylinders of india-rubberinclosing iron shafts or cores Z9, c. The shaft of the roller C is freeto move vertically in slots in the sides of the frame as in otherclothes wringing machines, and is held down by springs which areconcealed within the uprights A, A, and are governed by screws m, fm..To the shaft of one of the rollers B or O a crank (not represented) isto be applied for giving motion to the machine. These parts are allsimilar in arrangement and effect to the corresponding parts of otherand well known clothes wringing machines, which are familiar tomechanics.

In wringing machines of this character as hitherto constructeddifiiculty has been eX- perienced in keeping the rubber firm upon theshaft, so that it will not turn when pressure is applied. To obviatethis difficulty I provide washers, D, of the form shown in Fig'. 3, withprojecting spurs cl, d, arranged ra ially upon their faces and lplacethem upon the shafts Z9, c, driving them tightly against each end of therubber as shown, and key them fast to the shaft. The points or spurs (Z,are pressed into the ends of the rubber rollers and prevent them fromtwisting upon their shafts unless very great force be applied, but inconsequence of the little distance to which they project and of theirradial position they do not offer any obstacle to prevent the rubberproducing its useful effect upon the clothes, quite up to the washers.

Upon the side of A, in suitable bearings c, I mount a wooden roller, E,of the form represented, with its ends E, E', larger than the middle,which roller turns freely in its bearings. The object of this roller isto so elevate the clothes that the water expressed may fall freely, andalso to restrain or guide the clothes laterally, as they are passinginto the wringer, and by the use of this frictionless roller in lieu ofthe stationary guides commonly in use for this purpose to avoid theliability to tear which attends the employment of the latter.

In a conical tub having flutings upon the interior like Frenchs patentwashing machine above alluded to, the utings converge toward the apex ofthe cone and present a difficulty to the applying of a wringer thereto.To adapt my wringer to such a vessel, I so attach the legs a, a,'to theframe A, that they may be bent aside as shown. These legs are attachedby means of a thin steel plate I, or a series of such plates laidtogether to act as one, let into the center of the leg and the frame,and securely fastened in each. These platesl are about equal in width tothe thickness of the leg, and are so thin as to spring easily in theproper direction, and so broad as to possess the requisite strength inthe other direction. A space z', is allowed at the juncture of the legwith the frame, so that the former may be bent aside from theperpendicular by any sutlicient force, but. it cannot be sprung inanyother direction owing to the resistance oEered by the metal strips I tostrains in the direction of their edges. In placing the machine upon aconical fluted vessel, the legs stand in a position shown in full blacklines, but as it is pressed downward the legs a, a, by the yielding of Iadapt themselves to the taper of the grooves in the i A, by hingesinstead of the elastic strips I or tub or vessel, but hold the machinerm in the direction in Which the strain due to operating it is received.

' K, K, are thin boards placed so' as to form a guide or spout to conveythe Water Which is squeezed from the clothes back into the tub.

The legs a, may be attached to the frame by a thinner portion ofthemselves so as to perform the same office, but I prefer theconstruction shown.

The advantages due to the use of my roller E, E', in combination Withthe rubber rollers B, C, are that the clothes are properly guided intothe rollers B, C, near their centers Without liability to injury byrubbing against any fixed parts.

The advantages due to my yielding leg or legs a, are that the legs arethereby adapted to be fitted into the grooves lor flutings of f aconical fluted vessel by adapting them- .selves to the convergingposition of the flutlngs.

Having now fully described my invention what I claim as new therein anddesire to secure by Letters Patent isl. The employmentlin wringingmachines of the spool shaped guide rollers E, E, arranged to operate incombination with the soft surface pressure rollers B, C, substantiallyinthe manner and for the purpose herein set forth.

2. The employment on clothes wringing machines of the yielding leg orlegs a, adapted to yield in a plane parallel to the axes of the rollers,substantially in the manner and for the purpose herein set forth.
